Lesson Plan

• Identify the four principal methods used to measure business size (people employed, value of output/sales, volume of output/sales, capital employed).
• Explain the main advantages and limitations of each measurement method.
• Evaluate which method is most appropriate for a given industry scenario and justify the choice.

• Projector and screen
• Whiteboard and markers
• Printed worksheets with the comparative summary table
• Calculators
• Sample business data sheets (payroll, sales, production, asset statements)
• Handout summarising the four methods and their pros/cons

Begin by asking students how they would compare a local bakery with a multinational retailer. Link this to their prior knowledge of revenue and employee numbers, then state that today they will learn four specific ways to measure business size and when each is most useful. Success criteria: by the end of the lesson they will be able to select and justify the most appropriate size‑measurement method for a given business.

1. Do‑now (5') – Quick quiz on common ideas of business size; discuss answers.
2. Mini‑lecture (10') – Introduce the four methods with real‑world examples and brief formulae.
3. Group case‑study activity (15') – Each group receives a different industry scenario and data; they choose a method, perform calculations, and note assumptions.
4. Gallery walk & peer feedback (5') – Groups display their calculations; peers comment on the suitability and limitations.
5. Whole‑class discussion (10') – Consolidate advantages/limitations; compare methods across the cases.
6. Summary & exit ticket (5') – Students write which method they would use for a new tech start‑up and why.

Recap the four measurement methods and emphasise that no single method fits all contexts. Collect the exit tickets as a retrieval check. For homework, ask students to research a local business and produce a brief report selecting the most appropriate size‑measurement method, including at least one limitation they must consider.
